CARBON HOLDER FOR CONTINUOUS-FORM STATIONERY Filed Dec. 20, 1951 ATTORNEYSL Patented May 19, 1953 CARBON HOLDER FOR CONTINUOUS FORM STATIONERY Charles W. Hatfield, St. Louis, Mo., assignor to Standard Manifold Company, a corporation of Illinois Application December 20, 1951, Serial No. 262,588

3 Claims.

This invention relates to carbon holders for use with continuous-form stationery, and more particularly to a support for carbon holding blades.

The primary object of the invention is to provide an improved holder for carbon holding blades whereby th blades may be swung about their supporting posts to a position out of the stationery which will facilitate attachment of a fresh carbon supply to the blades.

Another object of the invention is to provide spacer members which will hold the blades apart when in writing position, so as to reduce the weight on the carbon interleaved stationery drawn through the device.

Another object of the invention is to provide closure members for the slots in the spacer members which will cooperate with the supporting posts in holding the blades at the desired angle in the stationery.

Still another object of the invention is to shape the ends of the carbon blades so that they may be turned ninety degrees without leaving the slots in the spacer members, but when turned a substantially greater distance will clear the spacer members and can be removed from the supporting posts.

The invention is illustrated in a preferred embodiment in the accompanying drawings, in which-- Figure 1 is a plan view of the devic with the blades in normal position and the stationery is indicated by broken lines; Fig. 2 is a front elevational view of the same; Fig. 3 is an end elevational view of the right end of the device, as viewed in Fig. 2; Fig. 4 is a vertical sectional view, taken as indicated at line 44 of Fig. 2; Fig. 5, a fragmentary plan view showing the blades turned to th position for renewing the carbon; and Fig. 6, a fragmentary plan view showing a carbon blade turned to a position where it may be removed from the posts.

In the embodiment illustrated, a channel-like base member I is provided with a pair of downwardly extending studs 8 for attachment to the carriage of a continuous-form writing machine. The base member is provided at opposite ends with a pair of upwardly extending posts 9, secured to the base member 1 by means of nuts [0.

A pair of spacer members II are also secured to the base member I by means of machine screws [2. Each of these spacer members is provided with a series of forwardly open slots l3, which may be closed by a headed pin [4 adapted to fit through a series of aligned vertical apertures in the front of the spacer members ll. Thin metal carbon blades have a hole near one end adapted to fit over one of the Posts 9.

As best shown in Fig. 1, when the blades are in operating position the blades are locked by the pins [4 against forward movement. With fanfold stationery, indicated by the broken lines at It, the blades are usually inclined rearwardly so that the carbon will be directed into the connected lateral folded edge of the stationery. When the device is used with separate strips of continuous-form stationery, the blades may extend at right angles to the edge of the stationery and project across the machine, so that the free end of the blade enters one of the slots in the remotely positioned spacer.

As shown in Figs. 5 and 6, the blades may be turned ninety degrees without leaving one of the slots I3, so that after the carbon has been removed it can be swung back into proper position without hunting for the proper slot. However, the end of the blade is cut away, as shown at I I, so that when turned to the position shown in Fig. 6, the blade will leave its slot and can be slipped upwardly off of the post 9.

In using the device, it is merely necessary to raise the pin M, as shown by dotted lines in Fig. 4, and the carbon and the blade may be swung to the position shown in Fig. 5, where the carbon sheet or carbon pack can be renewed easily. The blade can then be turned back to the position shown in Fig. 1, the pin 14 returned, and the device is ready for use.

The foregoing detailed description is given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, for some modifications will be obvious to those skilled in the art.

Iclaim:

1. A carbon holder for use with continuousform stationery comprising: a base member provided with a pair of spaced upwardly extending posts; a pair of spacer members mounted on said base member between said posts, each of said spacer members having forwardly open spaced slots; a plurality of carbon blades, each adapted to be pivotally mounted on one of said posts and swung into a spacer-member slot; and a releas able closure member at the front of each of the spacer members adapted to lock said carbon blades in the slots.

2. A device as specified in claim 1, in which the carbon blades are shaped so that they may be released and turned ninety degrees from their locked position without leaving the slots.

3. A device as specified in claim 1, in which the carbon blades are shaped so that they may be released and turned ninety degrees from their locked position without leaving th slots, and the end of each blade is shaped so that when turned substantially more than ninety degrees it will leave the slot for removal from the post.
